admissible, but h

min,AB
+ s
min,BB
is not. However, other admissible combinations for minimum edge distance c
min
and spacing s
min
for
h
min,A
or h
min,B
may be derived by linear interpolation between boundary values (see example for h
min,A
below).

For the HSL-3-SH M8, M10 and M12 diameters, the minimum slab thickness h
min,B
must be increased by 5 mm (

").
